Android 13 will notify you if your battery is being used excessively in the background. The second developer preview of Android 13 has been released by Google, which contains a number of new features, such as notification permissions, Bluetooth LE audio support and in-system components.

Even though long-lasting battery life is a must-have feature for every smartphone, a single rogue app may quickly deplete your power. Fortunately, it seems like Android 13 will have a feature that warns you if an app consumes too much power in the background, and this is good news.
The Android 13 Developer Preview has shown off a number of new features meant to extend the life of your phone. While not in direct use, an app drains your battery, and the system notifies you of this.
Because Android can already alert users when a foreground app is consuming excessive battery power, this may sound familiar. Non-Google-manufactured Android phones, such as those built by OnePlus, are also capable of running their own skinned versions of Android.
If an app consumes too much power over the course of a day, Android 13 phones will show a notice. Foreground services utilising a lot of battery, on the other hand, won’t show the notice, according to Google. Rather, if Android detects at least 20 hours of foreground services operating in a 24-hour period, you’ll get a message about it instead.
There will be no more than one notification per 24 hours. That is to say, you must develop the practise of not ignoring alerts at will. This has happened to me before, and I’m not the only one guilty of it.
New rules and constraints for background battery consumption will be included in Android 13 as a replacement for Google’s “excessive” notification trigger. Foreground services, work assignments, broadcast receivers and the app’s cache are all included in this, according to Google.
A few apps will be exempt from these restrictions: system applications and those that are installed on a companion device; VPNs; apps that have been assigned the Dialler role; app-owned devices and profiles; and apps that the user has specifically set in the settings to offer “unrestricted” functionality.
Preliminary Android 13 beta versions will be released in the second half of the month, according to Google’s timetable. The final stable version of the app is expected to be released in the autumn of this year.
You may now download and install Android 13 Developer Preview 1 on all of the above-mentioned devices. Improved privacy and security will be provided by Android 13’s new features. System picture picker in Android 13 enables users to share certain photos and movies with applications while preserving their personal material.
Android 13 will enable applications to find and connect to nearby devices via Wi-Fi even if they don’t have access to the user’s location. The Jetpack library and the Quick Settings Placement API, which enable active Quick Settings tiles to be put, are also part of Android 13’s modifications.
